There are no editing and/or deleting of a post within an active player bid thread allowed whatsoever during FAAB auctions.
Requests can be made of the Site Admin to perform a posting edit and/or deletion provided it is appropriate. Adjustment of a bid amount and/or years is inappropriate. Deletion of a post b/c you changed your mind on a player or accidentally bid on the wrong player is inappropriate. You can lobby Minnesota Twins, Chicago White Sox, Pittsburgh Pirates support for such adjustments if you feel an honest mistake has been made. Admin will only edit/delete posts that do not involve changing the structure of a bid.
Relative to the date of 11-15-2017 and beyond, if an instance of a posting edit and/or deletion is found within the confides of a Free Agent Auction Bidding, your name will be forward to Minnesota Twins, Chicago White Sox, and Pittsburgh Pirates for disciplinary action that they deem appropriate.
